is not material. Said openin of the guides F accommodate the `vertical siding st ems G, for the bed H of the platen carriage I. This bed ll isadjustable or folda'ble with the )laten carriage into a compact relationto t e keyboard or to the type bars of the new ty eivriter, but asshownherein, said bed an the platen carrlage'are adapted. to be adjusted intooverlying or overhanging relation to the keyboard, see dotted lilies inFig. 2, thereby disposing the phiten carriage in exceedingly compactrelatioli to the other parts-of the machine for convenienceintransportation. To secure this folduifg adjustment of the carriage bedto the p aten carringe, I have representedthe vertical movable stems Gas bein'r provided with horizontal arms r/ the liitterxeing fixedrigidly tothe' stems and extending outwardly from the same over the typebars C. The carriage H isv fastened rigidly to other horizontal arms g',which are disposed parallel tothe urina y and are connected pivotallytherewith in a suitable way as, for example, by pins or bolts sce Fig.4. lt is evident that the carriage d H is movable or shiftnble with thearms g when the latter are turned on the ivots in order to assume thedotted position of ig. 2, or the full linepositions shown by Fi 1 2 and0 of the drawin The lower eniiof the stems G extend be ow the iides F,as indicated by dotted linea iu liig. 3, said lower ends of the stemabeing connected by a horizontal bar or rod G', which is attached rigidlyto said lower ende of the stems and lies within the back of the frame A.

The carria bed H may be of any suitable or preferre construction, but asherein shown, it consists of a simple flat plate fiisteni-d ri idl tothe arma g. Said bed is provide at its middle with a slot li, and en therear edge of the bed is a guideway h having any suitable forni in crosssection. The aten carriage I may also be of any suita le or preferredconstruction, with a view to supporting a rot/ary platen or typecylinder J aa well as the various other parta required for operating theplaten in the manner well known to the art. Aa shown,

the l'aten carriage consista of the end lates i', w ich are joined at.their front an rear edges by rails i", the front rail being agited toreet directly'ii n the carriage H while the back rai is tltted in theideTi',

and plates of the carriage frame support a paper clamp J', which extendslongitudina ly ofthe platea carriage and has a section thereof curved toconform to the platen J, thereby disposing it into cooperative rela tionti'the platen tflilir the n ingtepa rin ecarria is r clamp, hover, maybe rfitdiod wpitgien wide limite.

As illustrative of a suitable type of this tension mechanism,I have shown t c carria bed H as provided with'a spring rum or spool K,see Fi 4. This drum is mounted on the. under side of the carriage hedfor rotation thereon imder the energy of its spring, and to the drum iscon' net-.tet a coi-il 'or strap le, which is anchored at its free endto a corner of the platen carriage l,as at le', wherebythe drum isadaptedto draw the platen carriage in the nequired direction. Thisplaten carriage is limited to endwise movement directly in a rectilinearpath by the described form of guide devices which are employed betweenVthe platen carriage and the carriage bed, und said carriage is given aste by step feed pementmechanism, which is adapted to be actuated by thetype bnr keys or by the s acing keys of the typewriter, als will presenty appear.

This eacapeineut mechanism must coperate with theplaten carriage when the latter is rained or mljimtedveiticall to aplurality of ditl'erent positions, in ori er that. the ae\'- eralwriting characters, such as the lower case letters, the up i r caseletters, the punctuationinarlc-i an the numerals. Said eseapementmechanism must, also permit of the adjimtmentv of the carriage bed tothe platen carriage to the required folded or unfolded jnmitions withouttakin the machine a )art or dismantling the wor ing parts tliereo undthe parts of the eacapement mechanism must be brought into coperativerelation to each other when the carriage bed and the platen carriage arereturned to their normal working positions.

yln the drawings aeeoinpanyin this application l have shown one type oesca ment mechanism which fultils these con itione. and I will nowproceed to deacribe the name in detail. An element of this eecapenientmechanism is a horizontal bar L ra in lengthwise of the carriage andattac iet thi-reto, pai-takin of the e|idwisomoveinent thereof, said bnricing provided in its bot! tom ed with a. .series of teeth forming arack. ilnother element of said escapenient mechanism is a dog carrier neresented more clearly by Figs. 4 and 7. id carrier is shown aa a flatplate or arm M, arranged referably on .the under side of the carriage H,to which it is connected pivotally in a suitable way, aa for example. bythe llt'.
